The Detector Group is conducting the following Detector Projects:
AGIPD (Adaptive Gain Integrating Pixel Detector) The AGIPD is a high speed detector intended for use at the European
XFEL. It allows single pulse imaging at 4.5 MHz frame rate with a
dynamic range allowing single photon detection and detection of more
than 10.000 12.4 keV photons in the same image.
BPM (Single Crystal Diamond Beam Position Monitors with RF Readout Electronics) Development of an X-ray Beam Position Monitor, based thin single-crystal diamonds, with four-quadrant electrodes and readout by modified Libera-Brilliance amplifier-filter electronics. The combination of fast diamond detectors and sophisticated signal processing at the radio-frequency of the PETRA-III ring allows for sensitivities of the beam-position down to a few tens of nano-meters, and up to frequencies of a few tens of kHz.
DSSC DEPMOS Sensor with Signal Compression, Non-linear gain DEPFET sensor for the energy range 0.5-6 keV capable of taking > 600 frames at 4.5 MHz; this is a development project for Eu-XFEL led by the MPG’s Semiconductor Laboratory.
Galapad (GaAs LArge Pixel Array Detector) Photon counting pixel detectors using heavier semiconductors, rather than silicon, could combine low noise and high speed with high detection efficiency with hard X-rays. The Galapad collaboration aims to develop gallium arsenide pixel detectors controlled by the LAMBDA readout system.
Germanium Pixel Detector Compared to other heavy semiconductors for hard X-ray detection, germanium sensors have the advantage of near-perfect material quality. In collaboration with Canberra, we are developing finely-pixelated photon counting germanium detectors. The LAMBDA readout system is designed to allow low-temperature operation of these sensors.
HiZPAD (Hi-Z sensors for Pixel Array Detectors) A range of heavy semiconductors such as GaAs, Ge and CdTe are available, but each material has strengths and weaknesses. The aim of the HiZPAD collaboration is to develop these materials for use at synchrotrons. As part of this collaboration, DESY have tested CdTe-based pixel detectors.
LAMBDA (Large Area Medipix Based Detector Array) LAMBDA (Large Area Medipix-Based Detector Array) – A photon-counting pixel detector system based on the Medipix3 readout chip, with a small pixel size (55µm) and high speed, deadtime-free readout. A single LAMBDA module has 1536 x 512 pixels, and multiple modules can be tiled to cover a large area.
PERCIVAL DESY initiated development of a multi-megapixel monolithic soft X-ray CMOS imager for synchrotron and FEL applications.
XNAP (X-ray Nanosecond resolution APD Pixel detector) X-ray Nano-second resolution APD Pixel Detector. Development of a 32 x 32 pixel array of fast Avalanche Photo Diodes, directly coupled to a pixelated readout chip. This 2D device will provide nano-second time resolution as well as mega-Hz framing rates.
